Antlia

The Antlia IR Pass 685nm filter is an absorption filter that allows infrared light with wavelengths of more than 685nm to pass through. It nicely complements the Antlia 850nm IR-Pass filter.

The Antlia IR Pass 850nm filter is an absorption filter that allows infrared light with wavelengths of more than 850nm to pass through. It nicely complements the Antlia 685nm IR-Pass filter.
